...lava and "black smokers" heat up the depths of the oceans, a controversy over whose model correctly predicts the shape of the earth's crust and mantle is heating up geologists at Harvard and around the country...
...football game. We stayed long enough to catch an overdose of Princetonian white picket fences and rabid Ivy League alums sporting fedoras, blue sportcoats with PRINCETON TIGER pins and drooling orange and black. If Atlantic City is one big dirty underbelly, then Princeton can safely be called the upper crust. Anyway, two versions of Americana over the space of two rainy New Jersey days. You can't beat that...
Actually, it might have been better to have presented The Importance of Being Earnest with an American flavor than to have created this harsh imitation of the upper crust English accent. It was one of the few flaws of this performance: this attempt to bridge the Atlantic gap was often wildly funny, but it was certainly not Wilde...
About 1,300 km (800 miles) long, the San Andreas Fault system separates two sections of the earth's crust known as plates. Like giant rafts, these plates glide across an expanse of superheated rock, viscous as tar, that surrounds the planet's molten outer core. At the rate of nearly 5 cm (2 in.) a year, the Pacific plate to the west of the San Andreas is slowly pushing north, past the North American plate on the east. One possible result: 60 million or so years from now, a sliver of the California coast that includes the megalopolis...
...today more sophisticated systems can alert people as much as a minute before a city starts to shake. "This is possible," explains Massachusetts Institute of Technology geophysicist M. Nafi Toksoz, "because seismic waves propagate through the earth's crust relatively slowly, 5 to 8 km/sec. With an extensive network of sensors, we can locate the epicenter and determine the magnitude of an earthquake. This gives us the opportunity to warn people in outlying areas." How long a warning depends on the distance from the epicenter. Had such a system been in place in Mexico, for example, residents of Mexico City...
